MUG(1) MUG(1)
NAME
mug - convert an image to a face icon
SYNOPSIS
mug [ file ]
DESCRIPTION
Mug reads a Plan 9 image(6) from file (or standard input if
there is no file) and displays a working version of the icon
a gray ramp, and a larger image (the `crop box'), all
derived from file. Selecting `Write' from the button-3 menu
will write the icon in face(6) format to standard output.
Imagine a 3x3 grid on the crop box. You can move an edge or
corner of the box by putting the mouse in the corresponding
section of the grid and dragging. Dragging in the middle
box in the grid translates the crop box. The mouse cursor
changes to tell you where you are.
The bar in the gray ramp controls the map from picture gray
levels to the output levels. The values along the bar are
mapped to 0 through 255 in the output. You can move the bar
vertically by grabbing the midsection or adjust the width by
grabbing an endpoint.
The current icon is shown in the bottom left corner, sur-
rounded by eight small empty boxes. You can save the set-
tings as they are by dragging the current icon into one of
the other boxes. You can restore the settings by dragging
an icon from one of the periphery boxes into the middle.
